Phase shift: Phase shift of voltage and current. Phase shift range within -
90°~90°. If programmed is positive it will be a leading power factor. If
programmed is negative it will be a lagging power factor.
Programming the load value (CS)
The user can press [Set] and set the input resistance value in the main interface
of CS mode. Directly set the present value through the knob or press numeric
keys to input the value. In case of wrong input by numeric keys, press
to delete the present input.
6.3.5 Constant Current +Constant Resistance (CC+CR)
The electronic load simulates the waveform distortion of some inverters by
sinking a nonlinear constant current and a resistor to meet their efficiency test
requirements.
